In the Prehistoric Days, I Became the Way of Heaven

Refining qi → building foundation → golden elixir → Nascent Soul → transforming into gods → transcending tribulations (hedao) → earthly immortal → heavenly immortal → golden immortal → Taiyi golden immortal → Daluo Jinxian → Quasi-sage → Hunyuan Daluo Jinxian (sage) → Heavenly Dao → Dao. Gu Ye traveled to a low-end version of the prehistoric world, where a small Daluo Golden Immortal could destroy the world, and there was no quasi-sage. As a ninth-level saint, Gu Ye would not restore the prehistoric world, and his strength would regress.
